BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to lip sync animation tools and more specifically it relates to a text-derived speech animation tool for producing simple, effective animations of digital media content that educate, entertain, and inform viewers by the presentation of speaking digital characters. The invention makes the creation of digital talking characters both easy and effective to produce.

2. Description of the Prior Art

It can be appreciated that lip sync animation tools have been in use for years. Typically, lip sync animation tools are comprised of Morph Magic (for 3D Studio Max), Morph Gizmo (for Lightwave), Shape Shifter (for Power Animator), Mimic (made by Lip Sinc Co.), Smirk (made by Lambsoft Co.), Famous Face (made by Famous Technology Co.), TalkMaster (made by Comhertz Co.), Automatic Lipsync (made by Fluent Speech Technologies Co.). Existing products generally can be divided into three categories, and problems with each are best described in relation to each category. The first category (A) are manual lip syncing products which generally require digital artists to manually sync up the animation of character lips to a pre-recorded sound voice track. Every new speech to be animated requires the same manual construction of animation information to attempt to synchronize with the voice track. The second category (B) is voice-driven products where a character animation of lip sync is automatically constructed from a processed analysis of the recorded speech of a real person. The third category (C) of products are text-driven speech animation programs, where a digital artist enters text as dialogue for the characters and the product automatically generates both a speech animation of the character and a sound dialogue track of the character voice.

The main problem with conventional lip sync animation tools are the complexity of trying to sync up lip motions to speech in a conscious manner, when in reality (as you speak), the lip motion is a totally unconscious and automatic derivative result of the intent to vocalize words. Category (A) products are most prone to this problem. The user of these products must try to consciously and logically do something that is fundamentally sub-conscious, automatic and never thought about in real life. The process is also time consuming and changes in the speech content require extensive efforts to modify the animation accordingly.

Another problem with conventional lip sync animation tools are the separation of the processes for generating the voice recording and performing the facial animation. Both Category (A) and (B) type products are prone to this problem. A voice talent person is recorded speaking the desired dialogue. This is done in a recording studio with professional audio recording specialists, equipment and facilities. The voice recording is then given to digital artists to use to create the facial animation. If at a later point in time, there is a desire or need to alter the dialogue content for any reason, the entire process of bringing voice talent into a recording studio must be repeated before the digital artist has a new sound track to work with to produce the new animation sequence. By making the voice recording a completely separate process requiring separate equipment, facilities and skilled employees, the digital animation process is unnecessarily complicated.

Another problem with conventional lip sync animation tools are the structure of the synthesized speech. Category (C) products are most prone to this problem. Products in this category currently use an unnatural division of sound components to translate text into synthesized speech, the audio portion of the resulting animation. Speech may be divided or broken down into phoneme modules (fundamental speech sounds) or syllabic modules (the syllables people actually use in real speech). A phoneme-based text translation process is simpler in that there are less phonemes than syllables in speech, but the result is unnatural because real speech is syllabic and all dramatic quality and character of human speech derives from modulation, emphasis, and pace of the syllables, not the phonemes.

While these devices may be suitable for the particular purpose which they address, they are not as suitable for producing simple, effective animations of digital media content that educate, entertain, and inform viewers by the presentation of speaking digital characters. The invention makes the creation of digital talking characters both easy and effective to produce.

In these respects, the text-derived speech animation tool according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of producing simple, effective animations of digital media content that educate, entertain, and inform viewers by the presentation of speaking digital characters. The invention makes the creation of digital talking characters both easy and effective to produce.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of lip sync animation tools now present in the prior art, the present invention provides a new text-derived speech animation tool construction wherein the same can be utilized for producing simple, effective animations of digital media content that educate, entertain, and inform viewers by the presentation of speaking digital characters. The invention makes the creation of digital talking characters both easy and effective to produce.

The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new text-derived speech animation tool that has many of the advantages of the lip sync animation tools mentioned heretofore and many novel features that result in a new text-derived speech animation tool which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art lip sync animation tools, either alone or in any combination thereof.

To attain this, the present invention generally comprises the Main Screen, the Dialogue Editing Screen, the Character Options, and the Phonetic Dictionary Editor. Main component 1 is the software user interface of the main program screen, and allows users to operate the essential controls to produce an animated speaking character. Commands and data input by the user from a keyboard or mouse-type device will be utilized by the Main Screen controls to generate the animation. The Dialogue Editing Screen is the expanded display of all the tools and variables the user has to create and edit the dialogue. The Character Options is the program component that allows users to select existing characters, modify them, import new characters for use, and assign a specific voice to the character. The Phonetic Dictionary Editor is the component that assists users in adding new words to the program dictionary for use in this program.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter.

In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.

A primary object of the present invention is to provide a text-derived speech animation tool that will overcome the shortcomings of the prior art devices.

An object of the present invention is to provide a text-derived speech animation tool for producing simple, effective animations of digital media content that educate, entertain, and inform viewers by the presentation of speaking digital characters. The invention makes the creation of digital talking characters both easy and effective to produce.

Another object is to provide a text-derived speech animation tool that allows users to create digital animated characters talking realistically from the simple introduction of text (written dialogue) and the simple editing of speech parameters (volume, pace, emphasis and inflection) that people consciously and intuitively do when they speak themselves.

Another object is to provide a text-derived speech animation tool that allows users to select from a library of existing characters if the user does not have the separate skills and tools to model and texture a digital character of their own design.

Another object is to provide a text-derived speech animation tool that allows users to easily add character models of their own design to the program if the user has tools for modeling and texturing.

Another object is to provide a text-derived speech animation tool that allows users to easily record new character voice samples of their preference (such as their own voice) into the program in a way that assures these new voice samples will easily and fully integrate with the functionality of the program.

Another object is to provide a text-derived speech animation tool that allows users to export the animation data and voice track to all other digital animation tools, as well as use such data and tracks in our product. Other animation packages have tools for character body animation, object animation, and particle animation beyond the specialized capability of our product, but our superior method of lip sync can be utilized in these other programs to improve their effectiveness in speech animation.

Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages be within the scope of the present invention.

To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, the attached figures illustrate a text-derived speech animation tool, which comprises the Main Screen, the Dialogue Editing Screen, the Character Options, and the Phonetic Dictionary Editor. Main component 1 is the software user interface of the main program screen, and allows users to operate the essential controls to produce an animated speaking character. Commands and data input by the user from a keyboard or mouse-type device will be utilized by the Main Screen controls to generate the animation. The Dialogue Editing Screen is the expanded display of all the tools and variables the user has to create and edit the dialogue. The Character Options is the program component that allows users to select existing characters, modify them, import new characters for use, and assign a specific voice to the character. The Phonetic Dictionary Editor is the component that assists users in adding new words to the program dictionary for use in this program.

Main component 1 is the software user interface of the main program screen, and allows users to operate the essential controls to produce an animated speaking character. Commands and data input by the user from a keyboard or mouse-type device will be utilized by the Main Screen controls to generate the animation. The Main Screen is the primary working window of this software program. Users will see this screen when they launch the program on their computer. Actual operation is by traditional computer processes and devices, including keyboard entry for letters, numbers, text and command shortcuts. Mouse-type cursor controllers can click on screen icons to activate, double-click, click-drag, and right-click in traditional manners. FIG. 1 illustrates the screen as seen by the user. FIG. 2 illustrates the Main Screen exploded to isolate groups of controls and allow for labeling these controls to reference the explanations in this patent document.

Basic Operating System tools 1 are the basic commands and procedural options of the operating system the computer is configured for (Win, Mac, Linux, Unix, etc.) Character 2 is the link to the Character Options and Dictionary 3 is the link to the Phonetic Dictionary. View Screens and Controls 4 are the elements which actually display the chosen character from a specific camera point of view, and allow the user to set preferences for this display. Object manipulation controls 5 are the tools that allow the user to position the character in the scene for a specific visual composition. Camera manipulation controls 6 allow the user to move or position the camera in the scene to frame the character(s) and scenic elements in a particular visual composition. Object options 7 are tools to allow the user to assign attributes to the characters or other scene objects that facilitate the process of creating the animations. Animation Render Controls 8 are the tools that allow the user to determine and initiate a specific type of render or visual compilation of the scene into a finished still image or finished animation sequence for inspection or for completion of the job. Animation Playback Controls 9 allow the user to control playback of any rendered animation by standard VCR type functions (PLAY, STOP, FAST FORWARD, REWIND, PAUSE, etc.) The Timeline control 10 allows the user to move through the time sequence of the animation so work on any scenic element can be performed at any specific time portion of the animation sequence. The Function Tab 11 allows the user to vary the working window to display specific detailed tools and options of a particular phase of the scene creation process. The access to the DIALOGUE EDITING SCREEN, the second Main Component, requires the DIALOGUE Tab 12 (one of the Function Tab group 11) to be selected, and then the Expand/Contract icon 13 is clicked on.

The Main Screen shown in FIG. 1 may be varied considerably in the layout of the tools. Given this is a software user interface; its assembly of components is not bound by physical connectedness or the design constraints of physics. Rather, the composition of components is predicated on software graphic user interface conventions as well as workflow ergonomics. Variations are infinite and not anticipated to affect the claims of uniqueness.

The Dialogue Editing Screen is the expanded display of all the tools and variables the user has to create and edit the dialogue. With the Dialogue Tab 12 selected, the user clicks on the Screen Expander 13 to shift to the second main component, the Dialogue Editing Screen. This screen also has Basic Operating System Tools 1, and the links to the Character Options 2 and Dictionary 3. Instead of the Main Screen View Screens and Controls 4, the Dialogue Editing Screen has Preview Windows 14 for two separate scene views (such as a group shot and a character close-up). Render controls 15 and Playback Controls 16 are positioned between the two Preview Windows 14 for ease of use. The Character ID 17 identifies which character (of several possible in a scene) is being edited. Controls to further expand the screen and allow User to edit character speech and animation are the Phonetics 18, Volume 19, Musical Pitch 20, Speech Pace 21, Expression 22, and Gestures 23.

The Dialogue Line 24 is where the User enters dialogue as text input from a keyboard. The invention automatically displays the typed text in syllabic form, spelled phonetically, alternating syllables in the Ch. A Phonetic 25 and Ch. B Phonetic 26 display lines. Volume of each syllable is displayed in the Ch. A Volume 27 and Ch. B Volume 28 lines. Speech Pace 29 indicates the relative duration of each syllable. Pace Zone 30 indicates the portion of the speech that is affected by an editing action. Mouth Expressions 31 is a line where non-vocal mouth animation (such as a smile) can be entered from the Action Library 37. The Eyes line 32 is where motions of the eyeballs and eyelids are added. The Eyebrows lines 33 and 34 (here shown expanded to each eyebrow can be controlled separately instead of both symmetrically moving) are where brow motions are added. Head Gestures 35 are where motions of the head are added. Neck Gestures 36 is where motions of the neck are added. All of these options are available for Character #2 38 and for Character #3 39. As illustrated in FIG. 5, the specialized parts of the Dialogue Editing Screen specifically related to the uniqueness of the invention and its operation are the elements in the Dialogue Line 24, the Ch. A Phonetic 25, the Ch. A Volume 27, the Ch. B Phonetic 26, the Ch. B Volume 28, the Speech Pace 29 and Pace Zone 30.

A Syllabic module 40 is the invention's graphic representation of the envelope of both motion and sound for that specific portion of the dialogue. This Syllabic Module 40 has a Ramp Up 41, a Sustain Zone 42, and a Ramp Down 43. Inside the Sustain Zone 42 is a phonetically spelled version of the syllable. Below the Syllabic Module are two Volume Settings, a Opening Volume Setting 44, and a Closing Volume Setting 45. The Volume settings for a Syllabic Module in Ch. A Phonetics 25 will always be in the Ch. A Volume line 27. Similarly, Volume Settings for a Syllabic Module in the Ch. B Phonetics line 26 will always be in the Ch. B Volume line 28. On the Speech Pace line 29, there are vertical bars used as Pace Edit Handles 46. In the Pace Zone line 30, there is a Zone Beginning 47, and a Zone Ending 48, which together define the portion of the dialogue affected by any editing action of the Pace Edit Handles 46. Variations of this screen may include an audio import feature and display so audio tracks (of sound effects, for example) can be imported and integrated with the program dialogue generation in a controlled time and volume relationship. Additionally, a display of musical notes and standard musical notation may be displayed to enhance the Musical Pitch element 20.

The Character Options is the program component that allows users to select existing characters, modify them, import new characters for use, and assign a specific voice to the character. From either the Main Screen Component or the Dialogue editing Component, the user can open the Character Options main component by clicking on Character 2 at the top right screen line. The Character Options display component replaces the Dialogue Editing portion of the screen leaving the components on top (the Basic Operating System Tools 1, the Character Options link 2, the Dictionary 3, the Preview Windows 14, Render Controls 15 and Playback Controls 16) intact. The Character Libraries section 49 has several library groups of characters listed, such as Animals 50. Activating Animals 50 will display a Pulldown Menu 51 of specific available characters. The MACAW Character 52 is shown selected. The Character Preview 53 then displays a visual image of the chosen character. Appearance Options 54 will list any variations of appearance available for the character. Example shown is four appearance options for types of Macaws. All use the same character geometry but have different surface colorations. Customize Appearance 55 allows the user to make alterations in the character appearance. Load Character 56 is a command to open the dialogue box that permits a specific character from an outside source to be brought into this program for use. Load Library 57 is a command for permitting a collection of characters to be brought into this program for use, and stored for reference as a library group. Voice Library 58 displays the list of human sampled voices currently in the program and available for use.

The Voice List 59 indicates the actual sampled voices. Accents 60 indicates the regional voice accent which the Phonetic Dictionary will apply in its translation of the typed text into pronounced speech. Templates 61 are the group of devices that assist a user in creating new character, appearance or voice components for customized program use. Mouth Guides 62 are the references to lip postures the program uses to create lip animation. Facial Motion Guides 63 are the references to facial postures and expressions used for facial gesturing. Image Map Guides 64 are the paint templates that indicate how a set of image texture maps are used by the program and provide methods for the user to paint over the existing colors with new patterns or colors and have them correctly fit the geometry of the chosen character. Voice Recording Guides 65 are the templates that assist a user in recording a new human voice into the program in a manner that allows the voice to be successfully integrated with program use. Variations of this will be primarily the number of characters available to use, the number of voices available, and the organization of these options into familiar groupings.

The Phonetic Dictionary Editor is the component that assists users in adding new words to the program dictionary for use in this program. From any of the other three main component screens, clicking on Dictionary 3 will open the display of the Phonetic Dictionary Editor. This component allows the user to introduce new words to the program (such as company names and trademark product names, for example) and designate to the program how the typed words will be translated into both vocal and animation results. The Selected Character Display 66 allows the user to see the character whose dialogue is being processed. The Current Voice 67 displays the voice in use from the Voice Library. Current Accent 68 displays the accent designated by the user for the current character because accent affects pronunciation of the words.

The Unknown Word Prompt Line 69 displays any and all words that have been entered as dialogue text and which the program cannot find in its phonetic dictionary. The word “Oaxaca” 79 is shown as an example, and is displayed here because in the Character #1 Dialogue Entry Line 24, the word “Oaxaca” 80 is highlighted in RED indicating the program has no phonetic translation of this word. The first of these words will be displayed in the window of 69 and the remainder of the unknown words can be seen and selected by clicking on the Pulldown List of Unknown Words 70. New Word Entry 71 is the panel where a user can introduce words in anticipation of their use, such as new fictional character names. The new word entered, or the unknown word displayed, can be given a pronunciation reference in the Pronunciation Entry 72 if the user is already familiar with the pronunciation syllables available and used by the program. A new user unsure of how a word is pronounced in this program process can use the samples, such as Sample Beginning 75 (which displays the word from the dictionary that has the most consecutive letters the same as the New Word starting from left to right), the Sample Ending 77 (which displays the word from the dictionary that has the most consecutive letters the same as the New Word starting from right to left, from end to beginning), and the Sample User Designated 76, which displays any word the user types in that may have phonetic parts similar to the New Word. The Phonetic Library 78 displays a list of all syllabic sounds the program uses to build words and a user can click/drag any syllable from this list into the New Word Pronunciation Entry 72 to assemble the syllabic modules that will result in the word spoken correctly. The Audio Test (AO) button 74 will assemble an audio example of all syllables entered in the Pronunciation Entry 72 and play it back for the user to hear how the designated pronunciation entry 72 will sound when spoken. If the spoken version is satisfactory, the ADD Command 73 will initiate the process of adding this new word and its pronunciation version to the library for program use.

The principle variation of this component is its adaptation to other languages, which will require different syllabic sound groups, a new dictionary and appropriate phonetic translation guides. The underlying operation principle will remain constant.

All connections of main and sub components of this invention one to another are based on software industry standard keyboard/cursor command actions upon a graphic user interface icon which allows all displayed tools, components or processes to be connected to one another. Variations of connections may occur by altering the software program code or programming language.

This invention, being a software product, obeys most conventional computer software basic operation processes and such processes will be described in industry standard terminology. The User opens the program and the Main Screen main component is displayed in a default mode of a new file or project absent of content. If the User desires to continue work on an existing project, the User will click on FILE from the Basic Operating System Tools 1 to get an OPEN FILE menu. This discussion will presume a new project is being initiated rather than an existing project being modified. The User starts a new project by selecting a character (or characters) to work with, by clicking on CHARACTERS 3 to go to the Character Options main component. It is displayed. The User will then open the various Character Libraries 49 and review the characters listed in the pulldown menu 51. Clicking on one listed character selects it. If there are options of appearance offered, as shown in Appearance Options 54, User can designate which option is preferred. The User then looks down the list of voices in the Voice Library 58 and selects one voice for the selected character. To see the chosen character speaking a standard reference line of dialogue in the designated voice, User will activate the Character Preview tools 53. If the User finds the chosen voice does not seem appropriate as spoken by the chosen character, User can select another voice and preview it. User can also assign any given voice a regional accent from the Accents List 60 and preview the chosen character speaking in the designated accent. If the User preferred to introduce a new character, new voice or modified character appearance to the program, that would be done with the Templates 61. Assuming the User is now satisfied with the character choice, appearance, voice and accent, clicking on the DIALOGUE TAB 12 returns the User to the Main Screen.

With the character now created and defined, the User will arrange the position of the character in the View Screens 4 by using the Object Manipulation Tools 5 that affect position, rotation and scale or size. Once the character is positioned in relation to any other characters or scenic elements, the Camera Manipulation Controls 6 are used to position the camera as desired for scenic composition. The User will now introduce dialogue for the selected character by clicking on the Dialogue Line 24 to activate it and then introduce the dialogue text by keyboard entry in conventional text format, writing in plain English what the character is to say. An animation of the chosen character speaking the typed dialogue can now be assembled by activating the Animation Render Controls 8, and then viewing the finished animation by using the Animation Playback Controls 9. However, the speech will most likely be bland and monotonous because the speech has not been edited for dramatic quality. To edit the speech, User clicks on the Screen Expander 13 to open the Dialogue Editing Screen main component. In the Dialogue Editing Screen main component, the User may open the editing options by clicking on any of the following: Phonetics 18, Volume 19, Musical Pitch 20, Speech Pace 21, Expressions 22 or Gestures 23.

Generally the four essential elements for dramatic speech are the Phonetics 18, Volume 19, Musical Pitch 20, and Speech Pace 21 and these four form one of the essential unique and superior aspects of this invention. Comparing our process with another prior art (Talkmaster, noted above in Prior Art), we will look at the word “Master”. In the Talkmaster system, the word “master” is phonetically broken down into five phonemes, “m”, “a”, “s”, “t”, and “r”. In our system, the word “master” is broken down into two syllabic modules, “mah” and “stir.” Our breakdown is both in the structure of actual speech and in the syllabic form users will immediately and intuitively understand when they edit volume and pace of this word. Normal speech of this word might tend to give emphasis to the first syllable “Mah,” so by our system, the volume of this syllable might be slightly increased from default level. You can also give a character quality to speaking this word by stretching the speech pace of the first syllable and allowing the volume to ascend on the Closing Volume Setting 45 for that syllable. The first syllable “mah” would be longer and of increasing volume, while the second syllable “stir” would be shorter and with a descending volume. Trying to do the same with a word broken into five parts would be counter-intuitive, cumbersome, and unnaturally inferior for a user.

Dramatic human speech is often given distinction by our conscious changes of musical pitch, even when the result is not singing but rather simply lyrical or melodic speaking. Some spoken emphasis is actually accomplished by shifts of pitch instead of shifts of volume or pace. A voice reflecting an angered or apprehensive emotion might lower the pitch of the spoken works, a linguistic quality generally described as a “gruff voice” (Gruff defined in The Random House Dictionary as “low and harsh”). An example is a person saying “Yes?” as a way of inquiring why another person is bothering him, and is displeased with the intrusion. Saying “Yes” in a normal pitch for that character voice would not convey displeasure. Lowering the pitch of that word will generally convey the displeasure. In this invention, voices are sampled from real persons, taking each syllabic module our program needs from the recorded sampled speech. That sampled voice has a certain natural pitch, a quality of high or low frequency for the average tonality, which generally can be equated with a musical note. Once that sampled speech is digitized, the program uses the natural pitch of that voice as the default pitch. The Musical Pitch 20 editing line of the program allows the user to pitch-shift the Syllabic Module 40, by a plus-or-minus numeric variable, and the digital voice sample is raised or lowered in pitch according to existent musical/audio technology processes. Our uniqueness herein is not new pitch-shifting audio technology, but rather the integration of this existent technology within our user interface as a simple and intuitive control that combines with the editing of volume and pace as the natural, conscious and easily understood processes of creating dramatic speech.

Returning to the operation of our invention, the program displays the typed dialogue from the Dialogue Line 24 in syllabic phonetic segments and further alternates these syllabic components on the Ch. A Phonetic Line 25 and the Ch. B Phonetic Line 26. The blend of sound from one syllable to the next, from Ch. A to Ch. B, is superior by this arrangement, as compared to arranging sounds in consecutive order on one audio line that prevents overlap of sounds. A/B overlapping and blending insures maximum flexibility in mixing the volume and speech pace of the sounds, because each Syllabic Module 40 has a Ramp Up 41 (the element fades in to full strength), a Sustain Zone 42 (where the element endures at full strength), and a Ramp Down 43 (where the element's strength fades to zero). Syllables from the same word must seamlessly blend one into the next, so the Ramp Down 43 of one syllabic Module 40 overlaps in time the Ramp Up 41 of the next Syllabic Module. Thus one syllabic sound in a word seamlessly blends into the next to produce fluent speech.

Where words are separated in the Dialogue Line 24 text by a space, the program allows the last syllable before a space to ramp down to zero with no blend to the next syllable, and the first syllable after the space ramps up only after the prior syllable fully ramped down. This results in the natural spacing of momentary silence between words that fluent speech requires. Testing the character speech as an animated audio and video compilation is done by using the Animation Render Controls 8. If any of the text entered on the Dialogue Line 24 is not found in the Phonetic Dictionary main component, those words will be displayed in red colored text and the User will be prompted to enter the Dictionary main component to create phonetic translations.

Clicking on Dictionary 3 will open the Phonetic Dictionary main component. All words without a phonetic translation in the dictionary will be displayed in the Unknown Word Prompt 69. The User may enter syllabic groups directly into the Pronunciation Entry 72 or can drag and drop syllables from the samples shown in the Sample Beginning 76, the Sample Ending 78, and the Sample User Designated 77. Once all words are phonetically defined, the User can go back to the Dialogue Editing Screen main component to edit the speech and hear the audio assembly of the edits. Dramatic editing of speech, for realistic and entertaining results, requires the variation of volume, pace and emphasis. Each Syllable Module 40 has two volume settings, an Opening Volume Setting 44 and a Closing Volume Setting 45. By default they are the same and set at “5,” which is a midpoint volume in the potential of 1-10. Users may increase the volume value of both of each individually, for effect. Some speech dramatically emphasizes one syllable louder than another, and this tool allows for that. Another dramatic speech effect has the volume rising or diminishing through the duration of a word, and the potential of setting different values for the Opening 44 and Closing 45 portions of a Syllabic Module Volume 40 creates this dramatic speech result.

Editing Speech Pace 21 further enhances the dramatic realism and quality of the speech. The User opens the Speech Pace component 21 and the Speech Pace line 29 and the Pace Zone line 30 are displayed. The User then sets the Pace Zone 30 to include only the portion of the dialogue text which requires adjustment, by click/dragging either the Zone Beginning icon 47 or the Zone Ending icon 48 to enclose only those portions of the dialogue to be edited. Once the Pace Zone 30 is defined, the User click/drags any Pace Edit Handle 46 in the Pace Zone 30 to expand or contract a portion of the Zone, resulting in lengthening or shortening the pace of the dialogue enclosed in the Zone. Combinations of varying volume and varying pace within a spoken passage result in the dramatic and realistic speech qualities that give characters a lifelike quality. If more than one character is utilized in this project, the second character is defined and programmed to talk by the same process outlined above for the first character. Once the character animation and dialogue are finalized, the Animation Render Controls 8 provide the tools for actually creating the animation in a standardized digital media audio/video file format for viewing within this application or export to be used in other digital audio/video editing and viewing programs.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention.
